CPT()

CPT

(

RenderState

)

Returns a RenderState for rendering the spotlight visualization.

PT()

PT

(

Texture

)

Returns a newly-generated Texture that renders a circular spot image as might be cast from the spotlight.

This may be projected onto target geometry (for instance, via NodePath::project_texture()) instead of actually enabling the light itself, as a cheesy way to make a high- resolution spot appear on the geometry.

pixel_width specifies the height and width of the new texture in pixels, full_radius is a value in the range 0..1 that indicates the relative size of the fully bright center spot, and fg and bg are the colors of the interior and exterior of the spot, respectively.
